Battery Life Test Kit includes essential materials and online instructions to assemble a basic electric circuit to test general purpose alkaline (dry cell) batteries.
Kit includes four battery holders, four lamp holders, 10 light bulbs, mounting board and enough screws.
You can use it to compare the life of AA batteries and record your data and make a bar chart.

Growing bacteria is the main experiment for many biology projects, which is why you need proper materials and supplies. This kit includes all the proper essentials to grow bacteria and perform several different science projects and experiments.

Construct your very own 3-feet tall DNA model with this kit. Included in this kit are materials for the construction of a DNA model, online instructions, and additional helpful information about DNA molecules.

Learn about the scientific world of slime, and discover your talents in Chemistry, polymers and material science. Get a feeling on how scientists connect small molecules of gases and liquids and make solid plastics and rubbers.

This kit includes materials to make 5 different slimes: Glooze, Wiggly Wonder, Power Putty, Flip-Flop slime, and more.
You may hear about chemicals such as Borax, Guar Gum, starch and polyvinyl acetate. But you will never know their real properties unless you perform hands-on experiments
such as those described in Slime Science kit. This set does not have a colorful box. Instructions are online.

Phenolphthalein C20H14O4 is an organic compound used as an acid-base indicator. This compound dissolves poorly in water, and therefore it is typically prepared using alcohol as a solvent.
The indicator has a visual transition interval that is colorless at pH 8.0, pink at 8.5 and red at pH 10.0 .

CLAMPH1 is a right angle clamp holder for connecting two rods up to 3/4" in diameter at right angles forming L or T shape. CLAMPH1 is made of die-cast alloy with plated brass thumbscrews. It can be clamped to rods up to 18mm diameter.

This Retort Clamp is perfect for providing a firm grip on objects of diameter
from 2 mm to 90 mm. The four pronged clamp made of cast alloy with a brass
thumbscrew, has cork lined jaws to improve grip without damage. The
overall length is approximately 240 mm. The clamp extension is a perfect
complement to any support stand.

These PH Indicator Sticks come in a pack of 100 and are color-fixed.
All you have to do is just dip in and read off! Use these pH sticks
for rapid measurement of pH in a liquid sample. pH indicator sticks are the most convenient type of pH papers or pH indicator papers.
Old Part# PHPAPER

For connecting two rods at right angles forming L or T shape.
Made of die-cast zinc alloy with plated brass thumbscrews. It can accept or be clamped to rods up to 18 mm diameter. This right-angle clamp or clamp holder is mainly used to connect different clamps to the vertical rod of a stand. This clamp can break by excessive force on screw.

pH indicator rolls are recommended for laboratory uses where higher quality indicators are expected. The clear plastic dispenser protects the indicator paper from environmental fumes that may change the color of paper. The color chart is inside the dispenser. Each roll contains 500cms of 7mm wide pH paper.
